The latest RAZR-looking, 5-row-keyboard-sliding, LTE-packing Droid incarnation - the Motorola Droid 4 - went live today on VZW.com and at Verizon Wireless stores nationwide. The Droid 4 is the first LTE-enabled device in the family which makes it much more appealing to those of you who have been shying away from Moto's iconic line due to data speed constraints.
